What is urban built up area and what does urban built up area mean

Urban area scope (urban area: general prefecture-level cities are the counties under their jurisdiction; Every city has a city district.

Urban Built-up Area Referred to as "Built-up Area", refers to the area within the urban administrative area that has actually been developed and constructed, and municipal public facilities and public facilities are basically available. The delineation of the scope of urban built-up areas should take into account factors such as natural topography, landforms, and the management boundaries of grass-roots administrative units, as well as the integrity of various urban land uses, and should be consistent with the geographical scope of population statistics as much as possible. Some built-up areas in the suburbs of the city, although not connected with the urban area, are very closely connected with the urban area, and have become an inseparable part of the city, and can also be regarded as urban built-up areas.

The built-up area of the city has different reflections in single-core cities and multi-town cities. In a single-core city, the built-up area is a concentrated and contiguous area that has been actually developed and constructed, and the municipal public facilities and public facilities are basically available, as well as a number of scattered areas that have been developed and constructed in a piece, and the municipal public facilities and public facilities are basically available. For a city and many towns, the built-up area is composed of several areas that have been developed and constructed in succession, and where municipal utilities and public facilities are basically available.

The division of urban built-up areas can reflect the scale, form and actual use of urban construction land in a certain time period, and provide a basis for analyzing and studying the current situation of land use, rational use of land in built-up areas and planning land for urban construction and development.

It is added that urban built-up area does not refer to the urban area where houses have been built, but refers to the area that has actually been developed and constructed, the municipal public facilities and public facilities are basically complete, and the urban living conditions are available. The purpose of delineating urban built-up areas is to reflect the scale, form and actual use of urban construction land at a certain stage, and to provide a basis for analyzing and studying the current situation of land use, rational use of land in built-up areas and planning land for urban construction and development.

The meaning of built-up area refers to the non-agricultural production and construction lot developed through the expropriated land and actual construction within the municipal administrative districtIt includes the urban construction land (such as airports, railway marshalling stations, sewage treatment plants, communication radio stations, etc.) that are scattered in the suburbs and have close ties with the city and have basically complete municipal public facilities.

Built-up area is the abbreviation of "urban built-up area", which refers to the area that has actually been developed and constructed in the urban administrative area, and has basic municipal public facilities and public facilities. China's statistical department uses built-up areas to reflect the size of a city's urbanized area. Specifically, it refers to the land that has been expropriated and the area of non-agricultural production and construction developed by actual construction within the scope of a municipal district.

It includes the urban construction land (such as airports, sewage treatment plants, communication stations) that are closely connected with cities scattered in suburban areas and have basically complete municipal public facilities.

Broadly speaking, built-up area refers to the area that has actually been built or is being built within the administrative scope of a city and is relatively concentrated. It is an objective reflection of the geographical distribution of urban construction and development. It includes the part of the urban area that is concentrated and contiguous, as well as other urban construction land scattered in the suburbs but closely related to the city.

The built-up area marks the size and size of the construction land in different periods of the city's development. China's urban built-up areas generally do not include large areas of farmland and areas that are not suitable for construction in urban areas.

Built-up areas of the cityIt refers to the non-agricultural production and construction lots that have been expropriated and developed through the expropriated land and actual construction within the municipal administrative district.

It includes urban areas that are concentrated in contiguous parts and scattered in the suburbs, and has close ties with the city.

Urban construction land with basic and complete municipal and public facilities (such as airports, railway marshalling yards, sewage treatment plants.

communication stations, etc.).

Built-up area is the abbreviation of urban construction area.

Built-up area refers to the land requisitioned within the municipal administrative area and the non-agricultural production and construction area developed by actual construction, which includes the urban construction land (such as airports, railway marshalling stations, sewage treatment plants, communication radio stations, etc.) that are scattered in the suburbs and have close ties with the city and have basically perfect municipal public facilities.

The scope of the built-up area generally refers to the area that can be included in the outer contour of the built-up area, that is, the realm range reached by the actual construction land of the city, so it is a closed and complete area, and the built-up area of a city with multiple towns scattered may be composed of several corresponding closed areas. Such as Lianyungang City and Zibo City.

Built-up area

Built-up area is a statistical concept, which refers to the non-agricultural production and construction area developed by expropriated land and actual construction within the municipal administrative district, which includes the concentrated and contiguous part of the urban area and the urban construction land scattered in the suburbs and the city that has close ties with the city and has basically perfect municipal public facilities.

That is, the area within the urban administrative area that has actually been developed and constructed, and the municipal public facilities and public facilities are basically available. That is, on the basis of urban areas, undeveloped land, inefficient land, unused land and idle land with good and dusty materials are removed.

The conditions for defining the urban area of the city are as follows:1. The dense building complex is regarded as the built-up area, and the indicators include the proportion of the area occupied by the building spine, the continuity of the spatial distribution of the building group, and the independent annihilation of the building.

2. With population density as the main index, the built-up area is required to have a certain population density, which is generally expressed by the number of population or population density.

3. On the basis of urban land use, according to the concentration of construction land and the obvious urbanization process, the land within a certain range is divided into built-up areas.

The built-up area refers to the area that has actually been developed and constructed in the urban administrative area, and the municipal public facilities and public facilities are basically available. For the core city, it includes concentrated contiguous parts and scattered several areas that have been built in patches, and municipal utilities and public facilities are basically available.

For a city and multiple towns, it consists of several contiguous developments and construction areas with basic municipal utilities and public facilities. Therefore, the scope of the built-up area usually refers to the area that can be included in the outer contour of the built-up area, that is, the scope of the actual construction land of the city.

First, the nature of rock deficiency is different.

1. Built-up area: refers to the land expropriated and the construction area of non-agricultural production developed by actual construction within the municipal administrative district.

2. Urban planning area: refers to the area near the urban area, suburbs and urban administrative area that needs to be controlled by urban construction and development, and the specific scope of the urban planning area shall be delineated by the urban people in the overall urban plan.

Second, the characteristics are different.

1. Built-up area: development and construction in patches; Municipal utilities and public facilities are basically available; Land for urban construction.

2. Urban planning area: The specific scope of the planning area shall be delineated by the relevant people in the overall urban planning, town overall planning, township planning and village planning, according to the level of urban and rural economic and social development and the needs of overall urban and rural development.

Third, the role is different.

1. Built-up area: The Chinese statistical department uses built-up area to reflect the size of a city's urbanized area.

2. Urban planning area: The main purpose of demarcating urban planning area is to control the use of urban construction land from the needs of urban long-term development, so as to ensure the gradual realization of the overall urban plan.
